I'm pretty bad about filling up too often, but I come from the 1/2 fill up generation. When it is down to 1/2 tank, unless I am on the road doing a long trip, at least a couple hundred miles, I will fill up at 1/2 tank. The habit came from my younger days when gas was $0.19 a gallon you could fill up for $5.00 or less most of the time. Sometimes we would get bad gas (water in it) because the State did not check tanks for contamination much back then, so we bought gas at different stations all the time so as not to get too much water in the tank. However, my wife never fills up till the light comes on and she has about 2.5 gallons left in the Tahoe. If you run it down this low all the time, I'd recommend you put a can of Berryman's B12 Chemtool through the tank once a month to take care of any water than be in the bottom of your tank. I do that to the Tahoe, and every two months for the Silverado.
